Most glucometers that I've seen are CR2032 or 2025. The trend
seems to be to make the meters smaller and smaller. Also,
they seem to be treated as largely disposable -- vendors wanting
to "hook" you on a new meter to get you "addicted" to THEIR
(highly profitable) test strips.

[One of the non-profits for which I've done volunteer work recycles
medical... "discards" (not actually "waste", just things that are
no longer "wanted" by hospitals, doctors, patients, etc. So, you
see a LOT of glucometers!]

some good multimeters,

My portable DMM's (venerable Simpson and disposable "1 digit" HD units)
have 9V batteries. The better (5 and 6 digit) DMM's are line powered.


The blood meters are about like the printers. Almost give them away so you
have to buy the strips made just for them. Just as many razors are. Give
away the razor and charge a high price for the blades.

Sort of hard to carry around a line powered DMM. Outside of lab work there
is seldom any need for more than the 4 1/2 digits of the Fluke meters that
run on 9 volt batteries.
